LUBRICATOR-CUP.

SPECIFICATION forming part of Letters Patent N 0.7 14,329, dated November 25, 1902.

Application filed July 23,1902. Serial No. 116,717. (No model.)

Be it known that I, EMILE LEOPOLD RAM- PAZZI, m achine-maker, acitizen of the Republic of France, residing at 48 Passage et Rue `Bernardin de St. Pierre, Havre, Seine-Infrieure, in the Republic of France, have invented certain new and useful Improvements in Lubricator-Cups, of which the following is a specification.

The present invention relates to an improved arrangement of lubricator having an y atmospherical valve housed in the lid.

The inVention consists in arranging the valve and its spring in the lid in combination with means which allow of the pressure of the spring on the valve being easily adjusted.

The accompanying drawings represent one form of lubricator-cup constructed according to my invention.

Figure 1 is an elevation, and Fig. 2 is a ver-` tical section, on the axial line or plane of the `said lubricator-cup.

` `My improved lubricator comprises a cup 1, having a bottom of round or conical shape and provided with a tubular part or nozzle 2, intended to be connected by any suitable pipe with the surface on which the member or part to be lubricated rests.- To the upper outer i edge of the cup isscrewed a lid 3, Within which is provided a chamber or recess 11 to receive a valve-box 12. `The said valve-box 12 is held with its opening downward by means of an obturator 6, on which is a screwthreaded socket 13, in which is screwed the `lower end of the valve-box 12, the said obturator 6 having an outer screw-threaded edge 14, by means of which it is screwed into the lower part of the lid 3.4 A\rubber or other elastic Washer 17 is preferably located bey tween the upper edge of obturator 6 and a corresponding shoulder 18 on the lid. The tops of valve-box 12 and the obturator 6 are provided with the apertures 9 and 10,.,re-

spectively,vfor the passage of the air which penetrates into the interior of lid 3 through the side openings 8. Within'thesaid valvebox 12 are arranged a ball-valve 4 and a spiral spring 5. The tension of spring can be adjusted by screwing the valve-box 12 more or lessinto the socket 13 of obturator 6 before inclosing the same under the said lid 3, so that ball 4 will obstruct more or less energetically the aperture 9 in the top of the said box. obturator is provided with a larger and squareshaped recess 16, in which can be inserted a correspondingly-shaped key (not shown) for the purpose of easily unscrewing the said obturator 6.

When once the valve-box 12, together with its obturator 6, is fixed in the lid 3 and the latter is screwed onto the cup 1, the lubricating matter placed in the lattercannot escape outside, and the outer air is able to penetrate through the apertures 8 and 9 and press valve 12 downward in order to take the place of the said lubricating matter as the latter is absorbed by the movable member or part to be lubricated.

To iill the cup with lubricating matter, the lid 3 is` unscrewed and taken off the cup, which is then completely open. Y

It will be observed that in the lubricatorcup constructed according to my invention the spring of the valve for admitting air is easily adjusted. It is, moreover, located away from the lubricating matter and is con sequently always free to operate.

The apertures or holes 8 for admitting air are preferably made under a projecting rim on the lid 3, so as to be protected and to The lower aperture or orifice 10 in the run no risk of being obstructed by dust or l other extraneous matter.

The round or conical shape of the bottom of the cup facilitates the tlow of consistent grease to the very last.

I claim- 1. A lubricator-cup having a hollow lid,'an obturator fixed inthe inner opening of the lid, a valve-box adj ustably fixed on the said obturator and within the lid, a valve, aspring inclosed in the said valve-box and causing the valve to bear on the under side of the top of said box, and apertures made, respectively, in the lid, the top of the valve-box, and the obturator.

2. A lubricator-cup having a hollow lid, a projecting rim or bead formed on the outer side of the upper part of the lid, lateral api ertures made in the lid just under the said rim or bead, an obturator fixed in the lid,`,

lid having an edge screw-threaded on the inside, an obturator having an outer screwthreaded surface which screws into the said screw-threaded. edge of the lid and having a socket with screw-threaded inner surface, a valve-box which screws into the said socket of the obturator, a spiral spring located in the said valve-box, a Valve located between the said spring and the underside of the top of the Valve-box, and a cup having a screwthreaded outer edge onto which screws the part of the edge of J@he lid located below the obturator.

4L. A lubrioator-cup having a hollow lid having a lower edge screw-threaded on the inside, an obturator having an outer screwthreaded Surface which screws into the said screw-threaded edge of the lid, a squareshaped recess in the lower surface of the obturator to receive a key, an inwardly-screwthreaded socket on the upper face of the obturator, a valve-box, screwed into the said socket, a spring-valve in said valve-box, and apertures made in the lid, in the top of the valve-box, and in the obturator below said box.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
